Hi Dave,<br>
Thank you for taking the time to look at BabyIDE. You spotted its
most novel part, the graphical<br>
interaction diagram. Alan coined the term object orientation: "<i>Thus
its semantics are a bit like having thousands and thousands of
computers all hooked together by a very fast network.</i>". The
interaction diagram shows such a network where objects have been
mustered to play their roles in the performance of a task or use
case. The behavior of the objects is coded in methods attached to
the roles.<br>
<br>
General questions and ideas about DCI can best be placed on <br>
<a class="moz-txt-link-abbreviated" href="mailto:object-composition@googlegroups.com">object-composition@googlegroups.com</a><br>
which represents several years of DCI knowledge and experience with
implementations in languages such as C++, C#, Marvin, Ruby, Scala,
Erlang, Javascript, Haxe, PHP, and Python. Smalltalk is not in this
list. This is surprising since Smalltalk has the most sophisticated
IDE for DCI and is its natural home.<br>

<pre wrap="">Hi all,
DCI is a programming paradigm with strong separation of concerns
* Classes are used for coding system state - what the system *is*.
* DCI Contexts are used for coding system behavior - what the system
*does*.
The DCI separation of concerns enhances code readability, supports
testing, and simplifies system extension.
BabyIDE is an IDE that supports the DCI separation of concerns by
viewing the code in practically independent projections.

I just installed BabyIdeAllInOne in my working trunk image. I have only
just started to look at it, but I have to say right away that the browser
is really interesting. It has a context view that provides an conventional
browser view, and you can switch to an interaction view that shows a graphical
interaction diagram. The objects in the diagram are live, and selecting one
displays its methods and their implementation.
